SI8662EC-AS1R

Digital Isolators Overview

The SI8662EC-AS1R is a dual-channel digital isolator from Skyworks Solutions, designed for robust signal transmission across isolation barriers. It features two independent channels with a typical propagation delay of 7 ns and a high common-mode transient immunity of 50 kV/µs. The device operates within a supply voltage range of 2.25 V to 5.5 V and supports data rates up to 150 Mbps. Packaged in an 8-lead SOIC (Wide) body, it provides electrical isolation ratings suitable for industrial and power electronics applications requiring reliable galvanic separation.

Digital Isolators Procurement Notes

Verify the specific suffix 'AS1R' corresponds to the required tape-and-reel packaging configuration and lead finish specifications. Confirm that the wide-body SOIC package dimensions align with your PCB footprint requirements. Ensure the operating temperature range meets your environmental constraints before finalizing procurement orders.

Digital Isolators Selection Notes

Select this component when dual-channel isolation with high CMTI is required for cost-sensitive designs. Consider the 150 Mbps data rate capability against your system's bandwidth needs. Evaluate the 5.5 V maximum supply voltage compatibility with your logic levels. Compare the 8-lead package size against available board space constraints.

Digital Isolators Part Context

This part belongs to Skyworks' Si86xx family of digital isolators, which utilize CMOS technology for low power consumption. The series offers various channel configurations and isolation voltages. The SI8662 specifically targets applications needing two isolated channels with moderate speed requirements.

Digital Isolators Replacement Considerations

Check Skyworks official documentation for direct pin-to-pin replacements such as the SI8662AB-IS1R or variants with different isolation voltage ratings. Verify functional equivalence regarding propagation delay and CMTI specs before substitution.
